12.18 The accompanying data on degree of spirituality for a sample of natural scientists and a sample of social scientists working at research universities appeared in the paper “Conflict Between Religion and Science among Academic Scientists” (Journal for the Scientific Study of Religion [2009]: 276–292). Assume that it is reasonable to regard these two samples as representative of natural and social scientists at research universities. Is there evidence that the spirituality category proportions are not the same for natural and social scientists? Test the relevant hypotheses using a significance level of .01.
